Method for manufacturing laminated iron core product

Abstract

A method for manufacturing a laminated iron core product includes laminating a plurality of iron core members which are punched from a first metal plate to form a laminate, removing oil adhering to the laminate, removing oil adhering to an end surface plate which is punched from a second metal plate, and disposing the end surface plate on an end surface of the laminate and welding the end surface plate and the laminate.

What is claimed is: 
     
       1. A method for manufacturing a laminated iron core product, the method comprising:
 laminating a plurality of iron core members which are punched from a first metal plate to form a laminate; 
 removing oil adhering to the laminate; 
 laminating a plurality of end surface plates which are punched from a second metal plate to form a temporary laminate; 
 removing oil adhering to an end surface plate which is punched from the second metal plate; and 
 disposing the end surface plate on an end surface of the laminate and welding the end surface plate and the laminate, wherein 
 removing the oil adhering to the end surface plate includes delaminating one end surface plate of the plurality of end surface plates from the temporary laminate and removing oil adhering to the one end surface plate. 
 
     
     
       2. The method for manufacturing the laminated iron core product according to  claim 1 , wherein removing the oil adhering to the end surface plate includes blowing gas onto the end surface plate to blow off the oil from the end surface plate. 
     
     
       3. The method for manufacturing the laminated iron core product according to  claim 1 , wherein removing the oil adhering to the laminate includes evaporating the oil from the laminate by subjecting the laminate to a heat treatment. 
     
     
       4. The method for manufacturing the laminated iron core product according to  claim 1 , wherein removing the oil adhering to the laminate includes blowing gas onto the laminate to blow off the oil from the laminate.
